Pressure cap

[harrison]

Morning all,
Can anyone tell me what is the correct PSI pressure cap to use on my cooling system.
I have an LS2 from 2006 GTO.
Thanks and regards.

Hi Terry, mine has a 15 psi cap I think.
Standard sort of pressure.
I'll double check later.

Mines also 15 psi.

Thanks for replies, at the moment mine is 13psi don't know what difference that would make but I think I will change to 15psi
Regards.

15 over 13 psi will give you a slightly higher boiling point.
Do you have a problem Terry?

Hi Kev,
No problem Thanks for asking.
I have been thinking about blinging up my engine bay and the header cap was one item I was looking at (gal at the moment)
Do you know of any UK companies that supply this sort of stuff, have been lookin on the web site in the US, some don't ship to the UK but of those that do customs and postage make them expensive.
best regards.
